to get can mean to arrive at place or to cause to arrive at a place. "I got home late last night." "The taxi got me home?"

"where it got us" means the place (where) that my negotiation (it) caused us to arrive to (got us). In this case, where is probably not a place, but a situation.

It means "I know where this has led us to." He is basically aware of the consequences/impact of his actions.
